Fatal colchicine poisoning by accidental ingestion of meadow saffron-case report.

A 62-year-old male died of colchicine poisoning after accidental ingestion of Colchicum autumnale (meadow saffron). He ate a salad of plant with green leaves regarded as wild garlic (Allium ursinum). A few hours later he developed symptoms of gastroenteritis and was admitted to hospital. In spite of gastric lavage, activated charcoal and supportive measures, multi-organ system failure developed over the next two days. Laboratory analysis showed highly elevated blood concentrations of hepatic enzymes, creatine kinase, lactate dehydrogenase and blood urea nitrogen, as well as leukocytopenia and thrombocytopenia. Mechanical ventilation, dopamine, noradrenaline, crystalloid solutions and fresh frozen plasma were applied but despite treatment the patient died five days after the ingestion. Post-mortem examination revealed hepatic centrilobular necrosis, nephrotoxic acute tubular necrosis, petechial bleeding in fatty tissue, blunt and shortened intestinal villi and cerebral toxic edema. Botanical identification of incriminated plant gave Colchicum autumnale which confirmed colchicine poisoning. Although the accidental ingestion of Colchicum autumnale is rare and to our knowledge only five such cases have been described in detail, this is the second fatal case in Croatia described in the last 3 years.

[The autumn crocus: two millenniums of actuality].

Colchicum holds a singular place in the History of Medicine. Many names were given through the ages: "ephemera", "finger of Hermes", "pater noster", "tue-chiens". Modern phytonyms clearly refer to the land of Colchis, a mythical place close to Armenia. Several centuries were needed to understand that, despite a frightening reputation, colchic was an elective treatment for the gout. In its long story, appears famous personages as Theophraste, Paulus Aeginata, Gilbertus Anglicus, the baron Storck and Benjamin Franklin. In modern times, colchicum has received besides gout, a wide array of new indications, among others: Behcet disease, collagen diseases and malignancies. A scarcely known chapter of genetics is the findings in 1889, by B. Pernice, an obscure physician from Palermo, of the major mitoic changes observed on gastric and intestinal mucosa of two dogs which had received large doses of colchicum. In spite of their scientific value, the works of Pernice remained largely ignored until 1949. Recent advances in colchiocotheraphy have shown fascinating new fields for research: thus in the familial Mediterranean fever, close to periodic disease, genetic disorder elective for subjects originated from all over Mediterranean and around Black Sea... the mythical country of Colchis. No other medicinal plant than colchic, except poppy, can give such records of perennial use in such a wide range of disorders.

Immunoassays for the quantitative determination of colchicine.

A radioimmunoassay as well as an enzyme immunoassay for the quantitation of fmol amounts of the alkaloid colchicine have been developed. The antiserum used for both assays was raised against a conjugate of colchicoside-bovine serum albumin. The crude serum was satisfactory for the performance of the radioimmunoassay. For the enzyme immunoassay, the antibodies had to be isolated and purified by Rivanol treatment with subsequent (NH4)2SO4 precipitation. The measuring range extends from 0.1 to 100 ng colchicine for the radioimmunoassay and from 0.05 to 350 ng for the enzyme immunoassay with detection limits of 125 fmol and 25 fmol, respectively. Both immunoassays cross reacted with colchicoside and 3-demethyl-colchicine up to 80%. The colchicine content in the newly established suspension culture of Colchicum variegatum as well as the influence of various culture media on the colchicine production of this cell culture were investigated with the radioimmunoassay. The enzyme immunoassay was well suited for the quantitation of colchicine in HPLC fractions of Gloriosa and Colchicum seed extracts allowing the rapid, sensitive, and precise determination of the substance under investigation. The preliminary experiments indicate that both colchicine immunoassays can be a useful tool for the analysis of colchicine in tissue and cell culture studies, for analysis of plant extracts as well as for biosynthetic investigations.

Accidental poisoning with autumn crocus.

We describe a case of a 43-yr-old female with severe multiorgan injury after accidental poisoning with Colchicum autumnale, which was mistaken for wild garlic (Allium ursinum). Both plants grow on damp meadows and can be confused in the spring when both plants have leaves but no blossoms. The autumn crocus contains colchicine, which inhibits cellular division. Treatment consisted of supportive care, antibiotic therapy, and granulocyte-directed growth factor. The patient was discharged from the hospital after three weeks. Three years after recovery from the acute poisoning, the patient continued to complain of muscle weakness and intermittent episodes of hair loss.

'Arthritis' in Byzantium (AD 324-1453): unknown information from non-medical literary sources.

OBJECTIVE--To compile and analyse information contained in non-medical texts of the Byzantine historians and chroniclers concerning arthritis, and to clarify the first use of Colchicum autumnale in the treatment of gout by the fifth century physician, Jacob Psychristus. CONCLUSIONS--This material gives an indication of the problem of arthritis and, in particular, a disease resembling gout that tyrannised a great number of the population in the Byzantine Empire (AD 324-1453). Contemporary historians and chroniclers maintain that the main causes of gout ('podagra') were the over-consumption of alcoholic drinks and food. Most relevant texts include anxiety and heredity among the aetiological factors of the disease. The incidence of this group of diseases among the Byzantine Emperors (it is certain that 14 of a total of 86 had a form of arthritis) and other officials of the State indicates that these diseases were a possible factor in certain political and military difficulties of the Empire.

[Poisoning by the autumn crocus plant].

Confirmed cases of poisoning resulting from the ingestion of Colchicum autumnale in mistake for Allium ursinum were analysed retrospectively. The study included 32 patients between 27 and 90 years. The severity of the intoxication was graded on the basis of the poisoning severity score (PSS). All the patients developed diarrhea and/or vomiting after a latency period of between 2 and 24 h. All those patients with a latency of > 9 h suffered only mild poisoning. If the leaves were boiled before being eaten, 64% of the patients suffered moderate, severe or fatal poisoning; when the leaves were eaten raw, only 33%. It is presumed that heating may promote the liberation of colchicines from the plant. Eight of the nine patients with severe or fatal poisoning were older than 65 years. A possible cause of the more serious course in the elderly may be a decrease in renal clearance. In addition, a diminished sense of smell may allow the absence of the typical garlic smell and taste of Allium ursinum to go unrecognised.
